False because the Pythagorean theorem can be used to find the missing lengths of ONLY RIGHT triangles, not any type.
Ok I’ll break this down so it’s easier to understand:
So you start of with $80
The first step is to find 20% off
An easy way to find 20% is to divide it by 5.
80/5= 16
And since it’s 20% OFF we subtract 16 from 80
80-16= 64
Next we need to do the coupon
It is $5 off so
64-5= 59
And finally the rebate which is $2
59-2= 57
Answer:
57
1) montly rate, r = 5% / 12 = 0.416% = 0.00416
2) capital, C = $ 450 = present value
3) time = 11 years => number of periods = 11 * 12 = 132
4) Formula: FV = C * (1 + r) ^ (number of periods)
5) Calculation: FV = $450 * ( 1 + 0.00416)^(132) = $ 779.07
Answer: $ 779.07
Let the number of baskets be x
Let the number of points be y
32 +3x = y
19 + 4x = y
Rearrange both equations then solve them as simultaneous equations
32 = y - 3x
19 = y - 4x
y - 3x = 32
- y - 4x = 19
x = 13
Substitute x into one of the equations
y - 3x = 32
y - (3 x 13) = 32
y - 39 = 32
y = 32 + 39
y = 71
Number of baskets (x) = 13
Number of points (y) = 71
